Emilio has touched every room in our home, installing crown molding, baseboards, door trim, and painting plus a full kitchen remodel. Emilio is a perfectionist and treats every project as if he is working on his own home. He is also a master at remodels, crown molding, baseboards, painting (interior and exterior) and general home repairs. Emilio is honest and is always looking for ways to reduce costs without affecting the quality of a project. I highly recommend Emilio for any project you have!

Emilio is very knowledgeable, thorough, and trustworthy. He's very pleasant and considerate. He explains things as the job progresses. Our job included such as dry rot, rotted posts, and painting. He was also careful to be aware of and apply HOA rules.
